Unlike Bollywood, stars and celebs don’t come-up ‘open’ about their relationship, in Kollywood. Though things looks like an open secret, stars keep denying their relationship, may be due to possible career crisis! Here are few star - - - couples to say, who are denying their relationship in public! Arya-Nayanthara Nayanthara made a rare public appearance at the audio launch of Amara Kaaviyam, starring Arya’s Brother under his production. They were seen together a lot in common, even at an after-party of an awards function which started indicating that there is something more than friendship. Siddharth-Samantha They were seen together so often in their circle, but they denied each and every time… atleast Samantha, who was protective about it. But her recent appearance at the audio launch for Siddharth's film Kaaviya Thalaivan said it all loud and clear. Vishal-Varalakshmi This pair was recently spotted, arguably when they were on a date, coz they seemed so cozy with each other, at the premiere of a movie. Rana-Trisha Are Rana Daggubatti & Trisha couples? This long standing question should be putting to rest. We can safely presume that they are. Their recent tweet picture of a selfie while boarding a flight recently, says lot more than intended.
